Did you use regsvr32 to register the DLL? hardikshahmca9 1-Jul-13 0:27am Yes , I have try to register the dll.

Solved C++ Com Problem Posted on 2011-10-04 Visual C++.NET MS SQL Server 2008 Windows XP 1 Verified Solution 12 Comments 1,903 Views Last Modified: 2012-08-13 Hi, I have a piece code which I wrote several years ago. This code was written on a XP system with VS2005. The code worked fine and in fact the existing .exe still works fine on some machines. The code was designed to sit on a remote machine and act as a server. Based upon requests, it would communicate with a third party database interface on the remote machine and respond with data to its clients. The portion of code which does the ADO resides in a dll. The main portion of the code manages the communications with the clients and calls functions in the ADO dll as required. Now, this code seems to work on some machines and not on others. I suspect the difference between target machines in 32 or 64 bit, though that may be totally wrong... On machines where it does not work I get an E_NOINTERFACE error. The code will still CoInitialize's and connects just fine. Its the call to: hresult = ptrRS.CreateInstance(__uuidof(Recordset)); which fails. I have included what I think are the relevant portions of code as well as the output from my trace calls. I have also attached a listing of CLSID's on my development machine, a machine on which it works and a machine in which it fails. My development machine is XP, 32 bit. The machine on which it fails is Windows 2008 Server R2 64-Bit. Thanks for all help in advance Phil webres-ole-Gimli.txt webres-ole-Gimli.txt webres-ole-spider.txt webres-ole-targe
